Hello all. Just got a new Mi4C 32GB and installed the SIM but I cannot get any mobile signal. The phone had EU developer version 5.11.19 and I have also tried 5.12.31 and the Greek 6.1.7 but no luck. I have also tried 2 SIMs but the result is the same. The SIM is partially recognized in the settings (data etc.) but the antenna does not seem to work. The same SIM works fine on my old phone.
